Keith Robinson, R. M. O’Leary, C. M. McDougal, Theodore Billings
1976, Miscellaneous Field Studies Map 773-H
A geochemical survey was conducted in the McCarthy quadrangle Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for gold from 764 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...

Bouguer gravity map of Alaska
David F. Barnes
1976, Open-File Report 76-70
The Bouguer gravity map of Alaska has been compiled from about 30,000 Alaska land gravity measurements plus approximately 40,000 km of surface-ship gravimeter traverses over the bordering continental shelves. The compilation thus represents nearly three times as much land data and ten times as much marine data as were available...

Mineral deposits and occurrences in the McCarthy Quadrangle, Alaska
E.M. MacKevett Jr.
1976, Miscellaneous Field Studies Map 773-B
The McCarthy quadrangle contains numerous and diverse mineral deposits in various geologic settings. Copper is the dominant mineral commodity, both historically and in terms of potential future production. Gold and silver are the only other metals that have been produced. The metalliferous deposits are concentrated in a northwest-trending belt along...
Geohydrology of the lowland lakes area, Anchorage, Alaska
Chester Zenone
1976, Water-Resources Investigations Report 76-22
Unconsolidated deposits, chiefly of glacial origin, make up the surficial geologic materials in the Anchorage lowland lakes area , the western part of the Anchorage glacial outwash plain. Postglacial accumulation of peat, commonly 5 to 10 feet thick, and the presence of ground water at or very near the surface...

The Orca Group is a thick, complexly deformed, sparsely fossiliferous sequence of flysch-like sedimentary and tholeiitic volcanic rocks of middle or late Paleocene age that crops out over an area of. roughly 21,000 km2 in the Prince William Sound region and the adjacent Chugach Mountains. The Orca Group also probably...

Microprobe study of olivine chromitites of the Goodnews Bay ultramafic complex, Alaska, and the occurrence of platinum
M. L. Bird, A. L. Clark
1976, Journal of Research of the U.S. Geological Survey (4) 717-725
Electron-microprobe analyses of the dunite and olivine chromitite of the ultramaflc complex at Goodnews Bay, Alaska, show that the chromite contains more ferrous and ferric iron than is found in chromite from alpine or stratiform complexes. The iron-magnesium distribution coefficients between chromite and olivine demonstrate that more ferrous iron...

1976, Journal of Research of the U.S. Geological Survey (4) 491-495
A 1-day reconnaissance of the Dietrich River, Alaska, included collection of benthic invertebrates. Three methods were used at each of five stations to increase sampling effectiveness and to evaluate each method. Chironomidae and Plecoptera comprised 91 percent of all individuals and 47 percent of all taxa in the combined faunal...
